Barry,
That issue + this commit:
$ git bisect bad
36c166f2bbb44c2987d8fb7385fbe9e2d1cfb0c8 is the first bad commit
commit 36c166f2bbb44c2987d8fb7385fbe9e2d1cfb0c8
Author: Barry Smith <bsm...@mcs.anl.gov>
Date: Sat Apr 10 13:40:10 2021 -0500
makes it actually impossible to ./configure on macOS.
Do we really expect all macOS users to know about the variable
MACOSX_DEPLOYMENT_TARGET?
Thanks,
Pierre
